A high pressure, screw-in, cartridge-style, proportional, spring-centered spool, pilot operated hydraulic directional valve.
When the HPE16-S67K is in neutral position, inlet port 3 is blocked while ports 2, 4 and 5 are connected to each other. On remote pilot signal at port 1, the valve’s spool shifts proportionally to the applied pilot pressure to allow flow from 3 to 4 through a load such as a hydraulic cylinder or motor, and then from 2 to 5 and to tank. Port 5 is to be used as a tank port only with maximum pressure of 69 bar (1000 psi). On remote pilot signal at 6, the spool shifts proportionally to the applied pressure in the opposite direction, reversing the flow direction.
The spool is non-symmetrical, providing only meter-in control.
• Hardened spool and cage for long life.
• Cost-effective cavity.
• Excellent metering characteristics.
• Good linearity.
• All HyPerformance™ products are tested to the rigorous standards of the NFPA specification T2.6.1 and are tested at a verification level of 90% and an assurance of 99%.
